摘要
在整个工作波段内具有较好的增益平坦度是对应用于波分复用光纤通信系统中的拉曼光纤放大器的一个基本要求。文章在分析RFA原理基础上,针对目前RFA的研究现状,分析了实现其增益平坦的几种方法,总结了国内外对RFA增益平坦化的研究,最后对其发展进行了展望。
A basic requirement for the Raman fiber amplifier used in the wavelength-division-multiplexing optical fiber communication system is that its gain spectrum must be flat in the operation band.Several methods to design the gain flatness of RFA are discussed according to the principle of RFA in recent research.The study on the gain flatness of RFA at home and abroad is summarized.The developing tendency of broad-band gain flatness of RFA is prospected.
